[texts]4. Eng Comparsion Shriram Gupta - SHRIRAM GUPTA & SARITA SINGH BHADAURIA
This paper compares and improves the bit error rate performance with the minimum mean squared error (MMSE) equalizer applied to wireless multiple antenna systems (MIMO) by using Orthogonal Frequency Division Multiplexing (OFDM). In Spite of much prior work on this subject, This reveal several new and surprising analytical results in terms of signal-to-noise ratio (SNR) by changing the OFDM parameters.

[texts]Robust Image Encryption Using Discrete Fractional Fourier Transform with Eigen Vector Decomposition Algorithm
Numerous methods  have been recently proposed in the literature for the encryption of 2-D information using optical systems based on the Fractional Fourier Transform. Encryption is one of the well known techniques to provide security in transmission of multimedia contents over the internet and wireless networks. There is a vast use of image in all areas so its security  is of great concern nowadays. Discrete Fractional Fourier Transform (DFRFT) generalization of the Discrete Fourier tr...

[texts]Detecting Original Image Using Histogram, DFT and SVM
Information hiding for covert communication is rapidly gaining momentum. With sophisticated techniques being developed in steganography, steganalysis needs to be universal. In this paper we propose Universal Steganalysis using Histogram, Discrete Fourier Transform and SVM (SHDFT). The stego image has irregular statistical characteristics as compare to cover image. Using Histogram and DFT, the statistical features are generated to train One- Class SVM to discriminate the cover and stego image...

[texts]An Optimized Transform for ECG Signal Compression
A significant feature of the coming digital era is theexponential increase in digital data, obtained from various  signals specially the biomedical signals such as electrocardiogram (ECG), electroencephalogram (EEG), electromyogram (EMG) etc. How to transmit or store these signals efficiently becomes the most important issue. A digital compression technique is often used to solve this problem. This paper proposed a comparative study of transform based approach for ECG signal compression...

[texts]On Fixed Point error analysis of FFT algorithm
In this correspondence the analysis of overall quantization loss for the Fast Fourier Transform (FFT) algorithms is extended to the case where the twiddle factor word length is different from the register word length. First, a statistical noise model to predict the Quantization error after the multiplication of two quantized signals, of different precision, is presented. This model is then applied to FFT algorithms...

 Interharmonics are the non-integral multiples of the system’s fundamental frequency. The interharmonic   components can be apprehended as the intermodulation of   the fundamental and harmonic components of the system with   any other frequency components introduced by the load. These   loads include static frequency converters, cyclo-converters,   induction motors, arc furnaces and all the loads not pulsating   synchronously with the fundamental frequency of the system...
